This week brought exciting developments in multi-agent AI systems that are changing how companies work. The biggest news came when the Eclipse Foundation introduced the Agent Definition Language (ADL) on October 28, 2025, making it easier for businesses to build and control AI agents. This new tool lets regular workers, not just computer experts, help design how AI agents behave.

In the technology world, LangGraph 1.0 released its first stable version in October 2025, helping developers build teams of AI agents that work together on complicated jobs. At the same time, Android Studio got new AI agent features to help developers create better apps faster, and Cursor 2.0 launched with smarter multi-agent tools in October.

Companies are seeing amazing results from agentic AI. In the medical field, 75 to 85 percent of work in drug companies can be helped or done by AI agents, which could make drug research 35 to 45 percent faster within five years. Meanwhile, OpenAI released a new AI agent called Aardvark in October that finds and fixes security problems automatically.

Baker Hughes explained how AI agents working together can think better and make fewer mistakes compared to single agents. The company showed real examples of AI agents helping oil and gas workers do their jobs faster. Industry experts predict that 96 percent of companies plan to use more agentic AI in the next year, and the market could grow to $200 billion by 2034.

Companies are also working on keeping AI agents safe and trustworthy. New guidelines focus on logging everything agents do, setting clear rules, and making sure humans can stop agents instantly if something goes wrong. Overall, this week showed that multi-agent systems are becoming real tools that companies use every day, not just exciting ideas about the future.
